Abstract
In series of pasture improvement studies with herbicides on nonarable hilly area, the effects of different cutting intervals (10, 20, 30 and 40 days) after glyphosate (2.9 kg/ha active ingredient) application on establishment and development of surface-sown orchardgrass(Dactylis glomerata L.) and ladino clover (Trifolium repens L.) was measured during 1983-1984. The cutting intervals of the existing shrubs after glyphosate application had no differential effect on establishment, seedling vigor, dry matter yield of surface-sown pasture species and botanical composition of improved pasture. Results showed that good control of the existing shrubs for surface-sown pasture species can be achieved by cutting the shrubs from 10 to 40 days after glyphosate application.
본 시험은 경운(耕耘)이 불가능한 산지(山地)에 있어서 제초제(除草劑)에 의한 초지개량시험(草地改良試驗)의 일환으로서 ha당 2.9kga,i의 Glyphosate를 철포(撤布)한 후(後)에 선점관목(先占灌木)을 그대로 방치한 것과 또 살포후 관목을 10, 20, 30, 40일 간격으로 예취제거(刈取除去)하였을 때 이러한 처리가 겉뿌림한 오차드그라스 및 라디노클로버 유식물(幼植物)의 정착(定着)과 생육(生育)에 어떠한 영향을 미치는가를 구명(究明)하기 위하여
